Loosen schema value restrictions for OKD compatibility

[shastaxc]

What would you like to be added?

OpenShift Kubernetes Distribution (OKD) automatically sets user and group for workloads. If setting these manually conflicts with the IDs OKD wants to use, it will throw an error. To help ensure compatibility, I generally just set these values to null and let OKD handle it. However, the Helm schema files do not allow null values. I would like the schemas to be updated to allow null values for the following settings:

podTemplate:
  spec:
    securityContext:
      fsGroup: null
      runAsUser: null

console:
  podSecurityContext:
    runAsUser: null
    fsGroup: null
    fsGroupChangePolicy: null

Why is this needed?

Compatibility with OpenShift Kubernetes Distribution.
